The maternal relationship between Mary Pomerville and her son
Milton James Beaudry is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DD.
The segmental (via DNA segment triangulation) and total DNA shared between DD and other confirmed descendants of
Joseph Marie Saucier/
Marie-Genevieve Tremblay is consistent with the expected ranges for their respective relationships. Since DD descends from Joseph Marie Saucier/Marie-Genevieve Tremblay through Mary Pomerville and her son Milton James Beaudry, the presence of significant shared DNA between DD and other known descendants of Joseph Marie Saucier/Marie-Genevieve Tremblay validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Joseph Marie Saucier/Marie-Genevieve Tremblay through Mary Pomerville to Milton James Beaudry, and ultimately to DD, confirming this direct ancestral connection through multiple generations.
